Description

Technical Field

[0001] This utility model relates to the field of yacht crane technology, specifically to a synchronously driven yacht crane winch device. Background Technology

[0002] A yacht crane is a specialized piece of equipment used for lifting yachts, playing a crucial role in the use, maintenance, and storage of yachts. It comes in various types, the most common being cantilever yacht cranes and gantry yacht cranes. Cantilever yacht cranes are typically installed at the dockside, featuring an extendable boom that allows for flexible lifting of yachts within a certain range, making them suitable for small docks and spaces with limited space.

[0003] Traditional yacht cranes typically use a single-drive mechanism, which involves lifting through multiple independent winches. However, synchronizing these multiple winches requires a complex control system and precise adjustments. If the synchronization is off, the yacht may shift position during the lifting process, potentially leading to a safety accident in severe cases. Utility Model Content

[0004] The purpose of this invention is to provide a synchronously driven yacht winch device, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A synchronously driven yacht winch includes a cantilever rotatably mounted on top of a column. Crossbeams are mounted on the outer surfaces of both sides of the cantilever, and first guide wheels are located on the lower sides of the crossbeams, with steel wire ropes wound around them. First fixing plates are mounted on both sides of the bottom of the cantilever, and a winding shaft is rotatably mounted between the two first fixing plates, with the ends of four steel wire ropes wound around the outer surface of the winding shaft. A first motor is mounted at the end of the cantilever, and the output shaft of the first motor is connected to the winding shaft.

[0007] Therefore, by having the ends of all four wire ropes wound and connected to the outer surface of the winding shaft, when the first motor drives the winding shaft to rotate, the purpose of simultaneously winding or releasing the four wire ropes can be achieved. This allows a single drive source to simultaneously drive four wire ropes to lift the yacht without the need for a complex control system and precise debugging. Furthermore, it ensures the stability of the yacht lifting and reduces the occurrence of safety accidents.

[0008] Furthermore, a first fixing post is installed at the bottom of the beam arm, and a second guide wheel is rotatably installed at the end of the first fixing post. A side plate is installed on the outer surface of the beam arm, and a second fixing post is installed on the lower surface of the side plate. A third guide wheel is rotatably installed at the end of the second fixing post, and the wire rope is simultaneously wound around the first guide wheel, the second guide wheel, and the third guide wheel.

[0009] Furthermore, a second fixing plate is installed on both sides of the bottom of the crossbeam arm, and a threaded rod is rotatably installed between the two second fixing plates. A base is installed on the outer surface of the threaded rod, and a first guide wheel is installed on the lower surface of the base. A second motor is installed on the outer surface of one of the second fixing plates, and the output shaft of the second motor is connected to the threaded rod.

[0010] Furthermore, recesses are provided on both outer surfaces of the crossbeam arm, and hanging plates are installed at the four corners of the upper surface of the base. Rollers are rotatably installed at the ends of the hanging plates, and the rollers are in rolling connection with the bottom wall of the recesses.

[0011] Furthermore, mounting plates are installed on the outer surfaces of both the first and second fixed columns, and a limit rod is rotatably mounted on the bottom of the mounting plate, with the outer surface of the limit rod in contact with the third guide wheel.

[0012] Furthermore, the first motor is a geared motor, and the second motor is a servo motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] 1. This utility model achieves the purpose of simultaneously winding or releasing the four wire ropes by winding the ends of the four wire ropes around the outer surface of the winding shaft when the first motor drives the winding shaft to rotate. This allows a single drive source to simultaneously drive the four wire ropes to lift the yacht without the need for a complex control system and precise debugging. It also ensures the stability of the yacht lifting and reduces the occurrence of safety accidents.

[0015] 2. This utility model uses a second motor to drive the threaded rod to rotate, which can adjust the position of the first guide wheel and change the lifting position of the wire rope. It can be adapted to the lifting operations of yachts of different sizes, significantly improving the flexibility of equipment use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a synchronously driven yacht winch device, including a cantilever 101 rotatably mounted on the top of a column 1. Crossbeam arms 102 are mounted on both outer surfaces of the cantilever 101. A first guide wheel 103 is provided on the lower side of each crossbeam arm 102, and steel wire ropes 107 are wound around the first guide wheel 103. First fixing plates 104 are mounted on both sides of the bottom of the cantilever 101. A winding shaft 105 is rotatably mounted between the two first fixing plates 104, and the ends of the four steel wire ropes 107 are wound around the outer surface of the winding shaft 105. A first motor 106 is mounted at the end of the cantilever 101, and the output shaft of the first motor 106 is connected to the winding shaft 105.

[0023] In use, the first motor 106 is started to drive the winding shaft 105 to rotate, thereby releasing the four steel wire ropes 107 at the same time. When the steel wire ropes 107 descend to the lowest point, the hooks (not shown in the figure) at their ends are hooked onto the straps wrapped around the yacht. Then the first motor 106 is started to rotate in the opposite direction, thereby winding up the four steel wire ropes 107 at the same time, so that the yacht can be lifted smoothly. Then the cantilever 101 rotates around the column 1 to lift the yacht from the shore into the river or from the river into the shore.

[0024] Preferably, a first fixing post 2 is installed at the bottom of the crossbeam arm 102, and a second guide wheel 201 is rotatably installed at the end of the first fixing post 2. A side plate 202 is installed on the outer surface of the crossbeam arm 102, a second fixing post 203 is installed on the lower surface of the side plate 202, a third guide wheel 204 is rotatably installed at the end of the second fixing post 203, and the wire rope 107 is simultaneously wound around the first guide wheel 103, the second guide wheel 201, and the third guide wheel 204.

[0025] In order to make the four wire ropes 107 staggered and wound on the winding shaft 105, the direction of the wire ropes 107 is guided by the second guide wheel 201 and the third guide wheel 204, changing their connection position with the winding shaft 105, so that the four first fixing plates 104 are staggered on the winding shaft 105, avoiding mutual interference.

[0026] Preferably, a second fixing plate 3 is installed on both sides of the bottom of the crossbeam arm 102, and a threaded rod 301 is rotatably installed between the two second fixing plates 3. A base 302 is installed on the outer surface of the threaded rod 301, and a first guide wheel 103 is installed on the lower surface of the base 302. A second motor 303 is installed on the outer surface of one of the second fixing plates 3, and the output shaft of the second motor 303 is connected to the threaded rod 301.

[0027] When the second motor 303 is started, it drives the threaded rod 301 to rotate. Under the action of the threaded connection, the base 302 can move along the length of the threaded rod 301 and adjust the position of the first guide wheel 103, thereby changing the lifting position of the wire rope 107. This allows for lifting operations on yachts of different sizes with high flexibility.

[0028] Preferably, recesses 4 are provided on both outer surfaces of the crossbeam arm 102, and hanging plates 401 are installed at the four corners of the upper surface of the base 302. Rollers 402 are rotatably installed at the ends of the hanging plates 401, and the rollers 402 are in rolling connection with the bottom wall of the recesses 4.

[0029] The recessed portion 4, the lifting plate 401, and the roller 402 allow the base 302 to slide along the length of the crossbeam arm 102. Since the roller 402 is in contact with the bottom wall of the recessed portion 4, it can support the base 302 and bear the weight of the yacht during the lifting process, thus avoiding direct stress on the threaded rod 301 and effectively extending the service life of the threaded rod 301 and related components.

[0030] Preferably, mounting plates 5 are installed on the outer surfaces of the first fixing post 2 and the second fixing post 203. A limit rod 501 is rotatably mounted on the bottom of the mounting plate 5, and the outer surface of the limit rod 501 is in contact with the third guide wheel 204.

[0031] Since both the second guide wheel 201 and the third guide wheel 204 are horizontally placed, a mounting plate 5 and a limiting rod 501 are provided to prevent the wire rope 107 from falling out of them, thus improving the safety of the lifting process. At the same time, the limiting rod 501 is rotatable, reducing friction with the guide wheels and the wire rope 107 and minimizing component wear.

[0032] Preferably, the first motor 106 is a geared motor and the second motor 303 is a servo motor.

[0033] The geared motor features low speed and high torque, enabling it to lift the yacht at a lower speed, ensuring the safety of the lifting operation. The servo motor features high precision, enabling precise adjustment of the position of the first guide wheel 103.
